Cleaning device for the barbed part of the card

The carding teeth of the carding machine penetrate the fiber bundle or gather the fibers for carding, and at the same time create the necessary conditions for separation and removal of debris, because the combing action of the mixed braking teeth will expose the debris on the surface of the fiber. With the clamping of the carding teeth, Impurities on the fiber surface are removed by centrifugal force. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit.

Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. The more thorough the combing effect, the better the impurity removal effect.

The licker-in rotates at high speed, and the air drives the surface layer of the rotating layer together with it. The air layer is called the boundary layer flow. The air flow is mixed with impurities and short fibers when the knife edge blade encounters dustfall, while the long fiber stabs on the hook serrated roller are still driven forward, and it is removed by dust removal on the moving blade of the surface impurities (Figure 2-16). After the fibers are separated into a single fiber development state, they are more easily affected by the airflow, and some of the fibers fall with impurities, but the specific gravity of the fibers is lighter than the impurities, and there is a greater resistance to air flow. The continuous rise causes the airflow to be brought back again, which is beneficial for the enterprise to save cotton.

The function of the device that traps the dust removal knife and the main trash receiver section, while the fiber and the collapse of both Torr by the airflow recovery section can be spun into fibers. The spines stop the flow through the boundary laminar at the back of the dust-knife barrier, increasing the pressure, part of the flow droplet, and forming the first region of the HFA. At the same time, a low pressure of the dust removal knife is formed on the other side, and the air flow rises to the suction surface of the punching drum to form a recovery area.

The height, position and angle of the dust removal knife should be adjustable. When the feeding cotton lap contains a lot of quality correction, the position of the dust removal knife can be appropriately lowered to increase the length of the first impurity area of ​​the enterprise, so that the impurities of these products can be removed here. When the feeding cotton lap contains a lot of small impurities, the dust removal knife can be raised and designed to hold the patient's fiber in time, reduce the amount of fiber torn in the safety first trash area, and increase the student's second trash area. .

When the gap between the dust removal knife and the licker-in is reduced, it is beneficial to remove impurities, but if the gap is too small, it will affect the whitening. The back of the dust collector and the horizontal angle (installation angle) use 70-110°. This angle is small, and it is easy to generate eddy current on the back of the knife edge, which will weaken the airflow on the back of the knife edge and the recovery effect on the inlet of the small leak bottom.

When there are many impurities in the lap, in order to make the knife more dependent and recover the fiber under the knife, in addition to reducing the dust removal knife, a larger installation angle should be adopted, that is, the so-called“Low knife and large angle measures”The function of the small drain is to support the fibers on the surface of the licker-in, and to remove the lint and dust through the mesh size of the drain. The leak bottom mesh should avoid paste village and sweet-scented osmanthus, and the leak bottom entrance should be relatively unobstructed, so as to avoid accumulation of fibers. Osmanthus fragrans or accumulated fiber cells will be inhaled or dropped by intermittent use, resulting in cloudy cotton mesh, uneven drying or whitening at the bottom of the leak.

The bottom leakage mesh paste plug will also directly affect the discharge of short fibers and cause uneven airflow.
